==================== READ THIS BEFORE CONTINUING ====================
=====================================================================

  If you don't know anything about Lua, I recommend taking some time to read through
  a guide. One possible example:
  - https://learnxinyminutes.com/docs/lua/

  And then you can explore or search through `:help lua-guide`
  - https://neovim.io/doc/user/lua-guide.html

Kickstart Guide:

I have left several `:help X` comments throughout the init.lua
You should run that command and read that help section for more information.
